Brief Summary:
The objective of this study is to evaluate the safety and effectiveness of Doppler guided uterine artery occlusion (D-UAO) for the reduction of fibroid associated bleeding.

Primary Outcome Measures :
  1. No Surgical Re-intervention [ Time Frame: Study completion ]
    Number of participants without any subsequent surgical procedure intended to manage fibroid symptoms performed. Potential procedures included surgical hysterectomy or dilatation and curettage (D&C) for treatment of menorrhagia; uterine artery embolization (UAE) or laparoscopic uterine artery occlusion; endometrial resection or ablation; myomectomy or myolysis.

  2. Improvement in Pictorial Blood Loss Assessment Chart (PBLAC) Score [ Time Frame: From baseline to 12 months ]
    Number of participants with a 50% or greater reduction in PBLAC score from baseline at 12 mo and a PBLAC score of less than 250. PBLAC is a simple validated semiquantitative method of measuring total menstrual blood loss using a pictorial representation of blood loss, where higher scores indicate more blood loss. This hybrid endpoint combined the reduction in PBLAC score with the total PBLAC score.

Secondary Outcome Measures :
  1. Mean Improvement in Health Related Quality of Life (HRQOL) Scores [ Time Frame: From baseline to 12 months ]
    Participants categorized as "better" in the total UFS-QOL questionnaire, indicating an overall improvement in health-related quality of life. On this scale, higher scores are indicative of better quality of life, with a maximum(best)score of 100 and a minimum (worst)score of 0. "Better" was defined as a change of +12 or more from baseline at 12 mo.

  2. Maintenance of Menses [ Time Frame: 12 months ]
    Number of participants with continuation of menstrual cycles without interruption for three consecutive months

  3. Procedural Satisfaction [ Time Frame: 12 months ]
    Number of participants with responses of either "satisfied" or "very satisfied" on a qualitative survey that ranged from "very dissatisfied" (worst) to "very satisfied" (best)

  4. Decrease in Fibroid Bulk [ Time Frame: From baseline to 12-months ]

    Number of participants with a minimum 15% decrease in fibroid bulk based on independent magnetic resonance imaging (MRI) review from baseline at 12 mo.

    Note: As per protocol, MRIs were planned only for subjects 1 - 40, 81 - 120, and 161-200.

  5. Mean Improvement in Uterine Fibroid Symptom Quality of Life (UFS-QOL) Symptom Severity Scores [ Time Frame: From baseline to 12 months ]
    Number of participants categorized as "better" in the UFS-QOL sympton severity questionnaire, indicating an overall improvement in fibroid related symptoms. On this scale, higher scores are indicative of increasing symptom distress, with a maximum(worst)score of 100 and a minimum (best)score of 0. "Better" was defined as a change of -11 or less from baseline at 12 mo.
